Black Bullet opening is awesome its done by FripSide, but some music sounds really dark. The anime is filled with side characters, and a lot of fight scenes. Everything looks beautiful and the fighting scenes are amazing. The animation really good as well. There are cute girls, you'll like them. The characters are excellent. I like loli in this anime because she's very cute. If you like the Toaru Majutsu no Index, you'll probably like Black Bullet. I recommend this anime for those who like to watch unique fighting styles. Sure, it's fun, and it seems to be one of the top anime in this season.
